A bacteriological study was done on the stool of 240 infants and young children. Ninety nine (41 2%) cases were found to be positive for causative agents of gastroenteritis. Stool cultures were positive for bacteria in 40% and for parasite in 1.3% patients. Thirty per cent of the cases had enteropathogenic E. coli (EPEC), followed by Proteus morganii (47%), Shigella (2.0%), Salmonella (1-6%), P...

The spores of Henneguya salminicola, a common tissue parasite of salmonid fishes in the northern hemisphere, were observed in stool specimens from two different patients with diarrhea. The spores' superficial resemblance to human spermatozoa resulted, in one instance, in an incorrect report, leading to suspicion of sexual abuse. H. salminicola spores and human spermatozoa can be differentiated ...

Giardia intestinalis is an intestinal parasite widely prevalent in children attending daycare centres worldwide and has been associated with undernutrition. Stool samples from 48 Guatemalan children (aged 1.5-7 years) attending participating daycare centres were analyzed over five weeks for presence of Giardia intestinalis using light microscopy, ELISA, and rapid dipstick test. Giardia prevalen...

Hydatid cyst is a zoonotic disease caused by Echinococcus granulosus, transferred through the oral-fecal pathway eating vegetables and food contaminated with dog stool containing eggs of parasite. most commonly found in liver; however, dissemination can occur other organs such as lung rarely heart, breast, thyroid, soft tissue neck, kidney. The surgical approach remains treatment choice hydatid...

Cystoisospora belli (C. belli) is an opportunistic protozoal parasite. It prevalent in tropical and subtropical areas of the world. frequently encountered immunocompromised patients with Acquired Immunodeficiency Syndrome (AIDS) other immunodeficiency illnesses. Infection usually occurs due to faecal contamination food water. Chronic severe watery diarrhoea C. infected patients. diagnosed by de...

The protistan parasite Perkinsus marinus is a severe pathogen of the oyster Crassostrea virginica along the east coast of the United States. Very few data have been collected, however, on the abundance of the parasite in environmental waters, limiting our understanding of P. marinus transmission dynamics. Real-time PCR assays with SybrGreen I as a label for detection were developed in this stud...

INTRODUCTION Sarcocystosis is mainly a veterinary problem; however, humans can serve as the definitive host for at least two species (Sarcocystis hominis and Sarcocystis suihominis). Intestinal infections occur in the definitive host after ingesting the intramuscular cysts (sarcocysts) in the intermediate host, which initiate sexual stages in the intestine that terminate in oocysts excreted in ...

In the present study we aimed to determine (i) frequency of Cryptosporidium species among patients with renal transplantation (RT) and human immunodeficiency virus (HIV) infection and (ii) relationship of the nature, severity, and duration of symptoms with different species and load of Cryptosporidium. Stool samples from 70 (42 RT and 28 HIV) and 140 immunocompromised patients with and without ...

Aim This study aimed to survey prevalence and clinical significance of Blastocystis among symptomatic and asymptomatic groups. Background Blastocystis is a prevalent microorganism that is found in intestine of human and majority of animals. However, most studies have failed to establish correlation between the presence of the parasite and clinical manifestations. Methods from Dec 2016 to Ju...

The parasite Cyclospora cayetanensis causes foodborne diarrheal illness. Here, we report draft genome sequences obtained from C. cayetanensis oocysts purified from a human stool sample. The genome assembly consists of 865 contigs with a total length of 44,563,857 bases. These sequences can facilitate the development of subtyping tools to aid outbreak investigations.
